Here is an option that might help. Don't use your grocery list, use a clone or copy of it. Create a "default" grocery list, could name it Grocery List. Then export the data, clone the list and import the date to the new cloned list...you could call the new list Grocery list Monday etc. Then when you needed to go shopping again on Friday, follow the steps again and you have a new list for Friday. Depending how long your lists are, might be easier to just un-check the boxes :)
